The Dormer B170 DIN 212 Form B machine reamer is a precise tool specifically designed for metalworking. With a nominal diameter of 1.52 mm and an overall length of 43 mm, this reamer provides an effective solution for creating fits within tight tolerances. The slight left-hand spiral and cylindrical shank allow for optimal chip removal and improved machining quality. The cutting length of 9 mm and working length of 20 mm are ideal for various applications in metal processing. Made from high-quality HSS-E material, this reamer is uncoated and suitable for machining carbon steel, steel alloys, cast iron, as well as aluminum and copper alloys. Compliance with the DIN 212 standard ensures high precision and reliability in application.

• Slight left-hand spiral for improved chip removal
• Neck relief grind for easier machining
• Diameter tolerance of 0/+0.004 mm for precise fits
• Suitable for a variety of materials, including steel and aluminum.
